Lin Feng, a deliveryman with advanced liver cancer, binds to the information collection system in despair and unlocks three key pieces of information every day. Using intelligence, he helped Chen Fei catch her spy husband, made millions by picking up ancient inkstones, cured his father's serious illness, and unexpectedly alleviated his own terminal illness. Dealing with beauties such as the charming antique shop owner Wen Miaoyu and the gentle doctor Song Ran, he skillfully used intelligence to repeatedly solve strange cases, expose corrupt officials, take down human trafficking dens, and smash espionage conspiracies. From being a lowly social worker to possessing wealth and beauty, Lin Feng counterattacked all the way and turned the Xia Kingdom into a no-go zone for spies.
